Lucy Stillman

Lucy Stillman is a recurring character in the Assassin's Creed franchise. In Assassin's Creed I she appeared as the operator of the Animus and a Templar that served under Warren Vidic. In Assassin's Creed II it is revealed that Lucy is an undercover Assassin working for the Templars. She later frees Desmond and leads him to fellow Assassins: Shaun Hastings and Rebecca Crane, who take Desmond to the Assassin-built Animus 2.0, where he spends most of Assassin's Creed II. At the end of Assassin's Creed: Brotherhood Lucy is killed by Desmond, who is seemingly being controlled by Juno through the Apple of Eden. More of her back story is shown in the Lost Archive DLC, where she is shown feeding information back to the Templars.

In Assassin's Creed III she is mentioned but does not appear, as Desmond reveals that he allowed Juno to kill Lucy, as he saw who she really was.Spoiler - Click to see/hide
